Abstract

A driver controller control circuit with a mechanical interlocking structure of electromagnetic valves includes a local cab control circuit, a remote cab control circuit and an intermediate garage. The local cab control circuit includes a local driver controller breaker, a local key bypass switch, a local driver controller key limit switch, a local electromagnetic valve, a local driver controller directional 0-position limit switch, a local cab key relay and a local driver controller activation relay. The remote cab control circuit includes a remote driver controller breaker, a remote key bypass switch, a remote driver controller key limit switch, a remote electromagnetic valve, a remote driver controller directional 0-position limit switch, a remote driver controller key relay and a remote cab activation relay. The driver controller control circuit ensures the interlocking function of the driver controllers at both ends, and reduces complexity of circuit design and occurrence of failure rate.
